Fuel cell water and heat management system

The invention relates to a fuel cell water and heat management system, comprising a fuel cell, a water pump and a storage water tank, the fuel cell includes two water flowing holes, the two water flowing holes are respectively communicated with the storage water tank, one of the water flowing holes is taken as a first water flowing hole, the first water flowing hole is communicated with the storage water tank by virtue of the water pump, a horizontal plane where the lowest point of an electric shock in the fuel cell is located is taken as a reference plane, volume of a part, above the reference plane, of the fuel cell is taken as first volume, at least one of the two water flowing holes is lower than the reference plane, at least a part of the storage water tank is lower than the referenceplane, a water flowing hole of the storage water tank is lower than the reference plane, volume of a part, lower than the reference plane, of the storage water tank is taken as second volume, and thesecond volume is not less
